JULIUS BATH, F LIPPSTADT, GERMANY, ASSIGNOR TO THE FIRM VEREINIGTE STAI-IL- PATENT; OFFICE WERKE AKTIENGESELLSGHAFT, 0E DUSSELDORF, GERMANY CABLE-TRANSPORT DRUM Application filed February 1,1930, Serial No. 425,147, and in Germany July 20, 1927.

I have filed a plications in Germany, July 20, 1927; in elgium, May 27, 1929; in

France, May 29, 1929; in Austria, May 10,

1929; and in Czechoslovakia, May 15, 1929.

For thetransportation of wire-rope, ca-

bles, wires, conducting wires and the like, in addition to wooden drums, drums made of iron have also been used which have the advantage over the wooden type of drums that 10 they may be used to a nearly unlimited extent and for any kind of transportation. As

a rule, the iron transport drums comprise two side walls of pressed iron sheet which are provided with ribs as stiffening means as well as with recesses for saving weight, both side walls being connected together through a pipe welded thereto.

It is the object of the present invention to provide a particularly advantageous construction of this type of drums. This new construction is particularly suitable for large and heavy drums.

The novel feature consists in the fact that the flange-like peripheries of the two side walls or end discs have corrugations" of a wave-like configuration for the purpose of securing better handling during transportation than is possible with drums having smooth flange surfaces. Besides, the wave go like shape has the further advantage that a wooden planking such as is used for the protection of the material to be transported may be easily attached thereto.

Figs. 1 and 2 of the annexed drawing show one embodiment of the invention; Fig. 1 being a cross section through a drum; and Fig. 2 being an end view thereof; a and b are the two outer side walls of the drum which by means of the impresse annular grooves 0 support the tube or cylindrical portion 03, the entire structure being held together by the bolts 6.

r In order to secure a better handling during transportation the outer flange-like peripheries f of the side walls are provided with corrugations of wave-shaped configuration and parallel to the axes of the discs a, 6, since it is evident that in transporting the drum, which is mostly effected by means of a 5a handspike, the wave-like form will afford a better grip for thelatter than smooth shape has the advantage that a wooden planking necessary for the protection'of the materials to be transported may be easily attached thereto.

The corrugations are of a slight depth, the depth being considerably less than the distance between the drum d and the edges of the discs, that is, the difl'erence in the diameter of the drum or cylindrical portion and the discs. The planking or lags fit the drum better than in a cylindrical drum because the edges of the planks may rest on theupper parts of adjacent corrugations, thus giving two points of contact, whereas only one point of contact is possible if the drum is truly cylindrical.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

A metallic cable transport drum, comprising a substantially cylindrical portion, disc portions at either end of said cylindrical portionand of considerably greater diameter than said cylindrical portion, said discs having outwardly extending flanges around the peripheries thereof, said flanges having cor- V rugations of wave-like configuration around their peripheries parallel to the axes of said discs and of a slight depth, said depth being less than the difference in the diameters of said cylindrical portion and of said discs, to

' aidin handling the drum and to permit the easy application of wooden planking to the drum.
